So I am doing practice problems from the text book and it states:(adsbygoogle = window.adsbygoogle || []).push({});

Given the thermochemical equation: 2Cu_{2}O(s) → 4Cu(s) + O_{2}, ΔH =+333.8 kJ/mol, calculate the mass of copper produced when 1.47 x 10^{4}kJ is consumed in this reaction

My attempt

(1.47 x 10^{4}kJ)/(33.8 kJ/mol )= 44 mol x 2 2 60=5.284 kg

BUT This is wrong and I dont know why...the answer is 11.2 kg
